Chicago Police have executed “multiple search warrants” in the investigation of 9-year-old Tyshawn Lee’s killing, a law enforcement source said Thursday.
Also, a “person of interest” has been released after he turned himself in to police Wednesday for questioning with his attorney, Sam Adam Jr.

Tyshawn may have been “lured and targeted” Monday afternoon in an alley in the 8000 block of South Damen as part of a series of retaliatory gang shootings, sources say.
